CONTAINER FOR DENTAL BURKS AND THE LIKE.

Application filed April 29, 1922. Serial No. 557,479.

To all whom 2'25 may concern:

Be it known that I, l/VILLIAM Rossnn, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Containers for Dental Burrs and the like, of which the following is a full, clear, and exact description.

This invention relates to acontainer for dental burrs and the like and has for its chief object to provide a case Or container which can be produced inexpensively, which supports the burrs in a manner such that the drilling ends can be readily observed so that the operator will know at a glance the particular burr desired for use, and which permits the burrs to be readily withdrawn and readily restored to the case after use or removal.

he container formed in accordance with my invention is preferably formed of one piece of sheet material, and in a manner such as to form pockets for the individual burrs or other articles-which may be supported in the case, the construction being such that the case can be formed by a stamping operation without requiring soldering or other fastening means at any point.

The invention may be briefly summarized as consisting in certain novel details of construction, and combinations and arrange-o ments of'parts "which will be described in the specification and set forth in the appended claims.

I In the accompanying sheet of drawings showing the preferred embodiment of the invention, Fig. 1 is a perspective view of the case with two dental burrs in place therein; 2 is atop plan view of the same; Fig. 3 is a longitudinal sectional view" of the same with a burr about to be restored to a pocket of the case; and Fig. 4 shows in elevation the shape of the blank from which the case is formed.

The case is flat and relatively thin. and is preferably formed from one piece of sheet material, preferably metal such as aluminum. In the embodiment shown it is provided with a flat front wall 10, a fluted rear wall 11 integral with the front wall, and a bottom 12 integral with the front wall 10. In fluting the rear wall 11, the metal is doubled upon itself at intervals as shown at 11 and formed substantially half round between the doubled portions so the outermost flute or pocket at one edge a of the case-the right hand end as the same is viewed in Fig. 2, and the fiat wall 10 has I its free marginal portion 10 folded part way around the flute or pocket at the other edge of the casethe left hand edge as the same is viewed in Fig. 2. The bottom 12 whichis integral with the front wall 10 as previously stated, is bent back at right angles and bears against the bottom edge of the fluted back wall 11 as shown in Fig. 3.

It will be observed that the fluted wall 11 extends up above the top of the flat front 0 wall 10, the upwardly projecting part serving as a guide which facilitates the restoration of the burrs in the pockets,.as will be readily apparent from an inspection "of Figs. 1 and 3, Fig. 3 showing a burr about to be restored in the pocket. In restoring the burr, the operator simply moves'the burr back until the bottom contacts with the upstanding wall at the rear of the desired pocket and then allows the burr t drop downward.

The case can, of course, be formed in ya 1 rious sizes, but when the case is used for holding dental burrs the height is such that the burrs project up above the case somewhat so that their drilling ends can be readily observed, making it easy for the operator t select the desired burr.

As already stated, the case is formed from one piece of metal, the blank being shown in Fig. 4, after the fluting operation, and as already egrplained, the case is formed and the parts are fastened together by a stamping or bending process, and no soldering or other fastening means is required. The construction is such that I am enabled to produce the cases very rapidly and inexpensively in one machine and in substantially a continuous operation, the metal be ing blanked out and fluted on one stroke,

after which the parts forming the walls 10, 11 and 12 are folded and essed together to form the finished case. ln this manner a metal strip can be fed in one side of the machine and the completed cases will be discharged from the opposite side.

If desired, the cases can be used as shipping packages as well as permanent containers for the burrs in the hands of the ultimate user. In that event the open top of the case and the projecting ends of the burrs may be enclosed in a slip cap to form a complete covering, though this is not essential to my invention.

Having described my invention, I claim:

1. A case or container for dental burrs and the like having front, back and bottom walls formed in one integral piece, one wall having transversely bent portions forming partitions and separated pockets, the other wall being integral with the endmost pocket forming portion of the first mentioned Wall at one edge of the casing and folded around a pocket forming portion thereof at the opposite edge of the casing.

2. A case or container for dental burrs and the like formed from one sheet of material, and provided with a front wall, back I and bottom walls integral with the front wall, the metal being bent to form transverse partitions forming separated pockets, said front and rear walls being integral at one edge of the case and having edge portions overlapping at the opposite edge of the case.

8. A case or container for dental burrs and the like formed from one sheet of material, and provided with a front wall, back and bottom Walls integral with the front wall, the metal of the rear wall being bent to form transverse partitions forming separated pockets, the rear wall being extended up above the front wall, the front wall bearing against the partition forming portions of the rear wall and the bottom wall bearing against the bottom ed 'e of the rear wall.

L. A case or container for dental burrs and the like formed from one piece of material having aflat front wall, a rear wall integral with the front wall and provided with flutes forming transverse partitions and separated pockets, and a bottom wall integral with the front wall bent to lie against the bottom edge of the fluted rear Wall.

5. A case or container for dental burrs and the like formed from one piece of material having a flat front Wall, a bottom Wall integral therewith, and a rear wall integral with the front wall and provided with flutes forming transverse partitions and separated pockets, the fluted rear wall projecting up above the front Wall.

6. A case or container for dental burrs and the like comprising a fluted rear Wall formed by doubling portions of the rear wall on itself leaving rounded pocket forming portions between the doubled portions, a front Wall which at one edge of the case is integral with the endmost pocket-forming portion, the opposite edge of the front wall being folded around the pocket-forming portion at the opposite edge of the case, and said case having a bottom portion integral with the front Wall and bent at right angles thereto so as to lie against the bottom edge of the fluted rear Wall.

7. A case or container for dental burrs and the like formed from one sheet of material and comprising front and rear walls integral along one side edge of the container and having edge portions contiguous along the opposite side edge thereof, one of said walls being fluted to form partitions and separated pockets, and a bottom wall integral with one ofsaid first mentioned Walls.

8. A case or container for dental burrs and the like formed from one sheet of material and comprising front and rear walls integral along one side edge of the container and having edge portions overlapping along the opposite side edge thereof, one of said walls being fluted to form partitions dividing the container into compartments, the other of said walls being flat, and a bottom wall in the form of a flange integral with the flat wall and bearing against the bottom edge of the fluted wall.

In testimony whereof, I hereunto affix my signature.

'VVILLIAM ROSSER.
